How to use Word Editor
A full-featured .docx editor in your browser. Open, edit, and save Word documents with formatting fidelity — plus comments, track changes, and AI-assisted writing (⌘K). The editing surface is TipTap on top of ProseMirror; .docx parsing happens locally via mammoth on import and the docx package on export. Single-user only — no real-time collab in the free tier.
Good for
- •Quick edits to a .docx when you don't have Word installed
- •Collaborative review using comments and tracked changes
- •Drafting with AI assistance — rewrite, summarise, translate selected text
- •Cleaning up a document received from someone else
- •Editing on a Chromebook, Linux box, or any device without Office
Not good for
- •Real-time collaboration with multiple cursors (single-user; Platform handles multi-user)
- •Macros, embedded Excel objects, or other Office-only features
- •Mail merge or any data-source-driven editing
- •Equations beyond basic inline math (advanced MathML round-trips poorly)
- •Heavy DTP-style layout with text frames, columns, or overlapping objects
Walkthrough
Step by step
- 01
Open or start fresh
Drop a .docx onto the canvas, or just start typing into the empty document. Auto-save runs every few seconds — your draft survives a refresh or accidental tab close.
- 02
Edit
Toolbar covers font, size, color, alignment, lists, tables, links, and images. Headings round-trip to Word. Slash commands (type /) open a quick block menu.
- 03
Insert images and tables
Drag-drop images directly into the document, or use the toolbar to insert. Tables support merge/split cells, header rows, and basic styling — all of which export cleanly to .docx.
- 04
Add comments + tracked changes
Select text and hit ⌘⇧M to comment, or toggle the Track Changes button in the rail to record edits as suggestions. Both round-trip to .docx and appear in Word's Review pane.
- 05
Use AI assist (⌘K)
Select text → ⌘K → pick an action: Improve, Make longer, Make shorter, Fix grammar, Summarise, More formal, More casual, Translate, or write a custom instruction. Streams in; accept or discard.
- 06
Save .docx
Click Save .docx in the topbar. Comments + tracked changes are preserved in the output and visible in Word. Filename defaults to your last open or 'untitled.docx'.
Tips
- •The Preview tab shows the document with full Word fidelity (fonts, colors, page layout). The Edit tab is the editable surface.
- •AI assist needs an OpenAI API key on the server. The button explains the setup if it's missing.
- •Toggle Track Changes off when you want your edits applied directly without recording.
- •Slash commands (type /) speed up structure changes — '/h1' for a heading, '/table 3x3' for a table.
- •Paste from Word or Google Docs preserves formatting; paste from plain-text sources comes in unformatted (use Cmd/Ctrl+Shift+V to force plain paste when you want it).
